A leading provider of polar expeditions in the cruise industry, Poseidon Expeditions offers a niche product for adventurous travelers: expedition cruises to remote and untouched parts of the world: the Arctic and Antarctica. Since 1999, we’ve offered unique one-of-a-kind polar voyages that combine the spirit of adventure with a generous measure of onboard comfort. Our small expedition ship Sea Spirit can navigate into protected channels and bays that are out of bounds to larger cruise ships. Whether you know exactly what expedition you want to embark on or need inspiration for the adventure of a lifetime, we’ll help find what’s best for you!
